Where I live, when you leave your yard work sneakers on the back screened-in porch, always give them a good bang and inspection before putting them on as there are spiders who are always looking for a place to set-up shop. And some of the spider species in these parts are the brown recluse and black widows. So I'm kinda in the habit of inspecting the foot wear before I insert foot. Now if I could only learn to do that with my mouth! (LOL)
